1. The intoxication produced by the intravenous injection of inert substances such as kaolin is due to protein split products derived from the serum proteins.
2. The kaolin acts as an adsorbing medium for the serum antiferment, bringing about an alteration in the ferment-antiferment balance.
3. The intoxication is accompanied by an increase in serum protease, and of proteoses.
4. The serum lipase, the amino-acids, and the total non-coagulable nitrogen show relatively little change.
5. The antiferment shows an initial increase, followed by a loss.
